My ex had her DNA tested for ancestry. It was very interesting. It turns out her family, in addition to being almost 50% Central American (indigenous American), is also Jewish, North African, Kenyan (Black African), Sardinia, French, Scandinavian, and Austronesian.
My daughter did a DNA test for ancestry too. In addition to the above, My daughter is Irish, Scottish, British, and Iberian. This means that I am Irish, Scottish, British, and Iberian. We knew about the Irish, Scottish, and British, but not the Iberian.
My ex's last name is Romero. Now her family knows that they are Jewish, Black, and North African, something they did not know before.
